The couple, who raises six children - Maddox, 11, Pax, nine, Zahara, eight, Shiloh, six, and Knox and Vivienne, four - will ink the name of their children and wedding date, reports contactmusic.com.
"They plan to have their tattoos done by a local French artist. They've designed a special motif that includes some of their vows and their children's names entwined in leaves, which will be in their own handwriting," a source said.
The marriage is expected to take place here before May, as Pitt will soon get a marriage licence.
